SASH-SUPPORTER.

Specification of Letters Patent No. 22,821, dated February 1, 1859.

To all whom it may concern:

Be it known that I, JOHN F. Pnuaonr, of Salem, in the county of Essexand State of Massachusetts, have invented an Improved Mode of Applying aSash-Supporter to its Sash and indow Frame; and I do hereby declare thatthe same is fully described and represented in the followingspecification and the accompanying drawings.

In such drawings, Figure 1 denotes a front view of a window frame andsash having my improvement. Fig. is a horizontal section taken throughthe rack bar.

My invention is specially designed for windows of railway passengercars, and in making it I have sought to obtain such a sash supporter orsuch an application of one, that its construction and mode of operationwould be apparent to any person on a glance of his or her eye 011 it.

The various kinds of sash supporters which are moreor less concealedwithin the sash and its frame, or in a boX or case applied to either aregenerally objectionable as they are either more or less destructive tothe frame or sash or are so covered as to render it difficult for theirmode of action to be understood by passengers. Furthermore, when theyoperate by spring pressure or friction against the jamb or groove theyare apt to either cause the window sash to stick too hard in the frame(particularly during damp weather) or to slide too easily.

In carrying out my invention I employ a lever catch and a toothed rack.The former I apply to the sash on its inner side, while the latter Iarrange against the inner side of the sash and fasten to the frame, sothat the said rack shall not only serve to maintain the sash within thegroove of the frame, but in connection with the catch operate to hold itat any desirable height in the frame, both rack and latch being in plainsight of a person, whenever he may attempt to raise the sash from itsinner side.

In the drawings A, denotes the window frame, and B, the lower sash, a,and Z), being the two grooves in which such sash is held and travelswhile being either elevated or depressed. A gravitating lever catch G isapplied to the inner side of the sash, and turns on a screw (l, thelonger arm 6, of the catch being heavier than the shorter one, f, whichacts with the teeth of the rack bar D, which is arranged against thesash and so as to constitute the inner boundary of the groove (4, and beentirely outside of the said groove. The said rack bar is fastened tothe jamb g, by screws 7b, 72, h, and should be made of metal. The rackbar thus answers a twofold purpose, that is, it holds the sash in thegroove, and in connection with the lever catch supports the sash whenraised in the groove. Its arrangement with that of the catch enablestheir construction and mode of operation to be readily understood by anyperson as soon as he may cast his eye upon them. The utility of sucharrangement, therefore is one, which not only is great but readilyapparent;

I do not claim the invention of a rack and a catch; nor the arrangementof a rack or its equivalent in the grooved jamb of the window frame soas to be covered by the sash while being raised, whether such rack beplaced on the bottom of the groove and against the edges of the sash oragainst the rear side of the groove and against the rear or outer sideof the sash, but,

lVhat I do claim is My improved application or arrangement of the rackbar, D, with reference not only to the groove, a, of the window frame,but to the inner side of the sash, B, and to the catch applied theretoas describedthe rack bar under such arrangement not only being in fullview with the catch at any altitude in which the window sash may beplaced in the frame, bht operating notonly to support the sash at suchaltitude but to maintain it within the groove 64, as specified.
